Why can't I use my iTunes gift card to purchase an app?

Question

I received a $15 itunes gift card for my birthday and I redeemed the card on iTunes. The $15 is in my account but I can't use it to purchase an app for my mac at the app store. I heard other people had problems with the itunes and app store connections too. However, my friend had purchased an app with the itunes redeemed credit. Am I stuck being able to use it only for itunes purchases? Any answers?

Answer 1

This is incorrect.
A. ITUNES STORE, MAC APP STORE, APP STORE, AND IBOOKSTORE TERMS OF SALE
PAYMENTS, TAXES, AND REFUND POLICY
The iTunes Store, Mac App Store, App Store, and iBookstore services (“Services”) accept these forms of payment: credit cards issued by U.S. banks, payments through your PayPal account, iTunes Cards, iTunes Store Gift Certificates, Content Codes, and Allowance Account balances. If a credit card or your PayPal account is being used for a transaction, Apple may obtain preapproval for an amount up to the amount of the order. Billing occurs at the time of or shortly after your transaction. If you are using 1-Click purchasing or your PayPal account, your order may be authorized and billed in increments during one purchasing session, so it may appear as multiple orders on your statement. If an iTunes Card, iTunes Store Gift Certificate, or Allowance Account is used for a transaction, the amount is deducted at the time of your transaction. When making purchases, content credits are used first, followed by Gift Certificate, iTunes Card, or Allowance Account credits; your credit card or PayPal account is then charged for any remaining balance.
